Please let me know what is wrong with the below query. I get a message saying function is missing a comma.

SELECT ALL;
        XPAT.PAT_ID                    AS PAT_ID_X,;
        IIF(XPAT.TMPATINFO like '4000%', XPAT.PAT_ID, XPAT.TMPATINFO),;
        XPAT.TMPATINFO                 AS XTMPATINFO;
  FROM "XPAT" XPAT;
  INTO CURSOR EA_T
